This project started in November and didn't finish until February, as most of the clear nights we've had this winter have been too windy for imaging. Tonight, for example. This is 18 hours via a CPC1100/SXVR-H694. Full details are with the image on the pBase site.

I'm still getting narrowband figured out, and this one seems a bit garish to me, maybe because the SII signal is so strong. I'd be very interested in seeing your processing of the data. For anyone who wants to try it, a zip file of the calibrated stacks is here:

Thanks, everyone. It's always very interesting to see how other people process the data. As for me, I used the standard ESO Colour Composite action for the color merge, and as I'm sure you can guess I stretched the curves on the OIII/blue pretty hard. I also added one part of Bob Franke's gold-turquoise action to shift the green to slightly orange-gold. Then I used JPM's StarRemove action to create a starless layer, subtracted that from the original to yield a stars-only image that I used to mask out the stars prior to deconvolution of the nebulosity with AstraImage. All in all a pretty good learning experience.

Peter, despite 40 years in this hobby I never heard of this target before I began imaging. Seriously, the Jellyfish Nebula?
